Embolic Drug-Eluting Beads
for the Treatment of Liver Cancer
DESCRIPTION
DC Bead and DC BeadM1 comprise a range of hydrogel microspheres that are biocompatible, hydrophilic,
non-resorbable, and precisely calibrated. They are CE Mark approved for loading with doxorubicin and irinotecan which
is released in a controlled manner after embolisation. DC Bead and DC BeadM1 are produced from polyvinyl alcohol and
are blue-tinted to aid with visualisation during preparation and loading.

INDICATIONS
DC Bead is intended to be loaded with doxorubicin
for the purpose of:
•
Embolisation of vessels supplying malignant
hypervascularised tumour(s)
®
•Delivery of a local, controlled, sustained dose of
doxorubicin to the tumour(s)
DC Bead is also intended to be loaded with
irinotecan for the purpose of:
•
Embolisation of vessels supplying malignant
colorectal cancer metastasised to the liver (mCRC)
®
•
Delivery of a local, controlled, sustained dose
of irinotecan to the mCRC
™
DC BeadM1 is primarily intended as an embolic
agent to treat vessels supplying malignant
colorectal cancer metastasised to the liver (mCRC)
and malignant hypervascularised tumour(s).
™
•
DC BeadM1 is compatible with irinotecan, which
can be loaded prior to embolisation and then, as
a secondary action, elute a local, controlled and
sustained dose to the mCRC after embolisation
™
•
DC BeadM1 is also compatible with doxorubicin,
which can be loaded prior to embolisation and then,
as a secondary action, elute a local, controlled and
sustained dose to the tumour after embolisation
™
Notes: Both products and/or all indications may not be available in your territory. DC Bead and DC BeadM1 are not cleared by the FDA for sale or distribution
in the USA. DC Bead and DC BeadM1 may be loaded with a drug product, to elute a local dose of drug to tumour sites after embolisation. It is the doctor’s
responsibility to give due consideration to the details contained in the drug product marketing authorisation in deciding which drug to load DC Bead /
DC BeadM1 with and whether loading with that drug is appropriate for the patient under his/her care. The relevant Summary of Product Characteristics
(SmPC) must be consulted. The type and dose of drug should also be assessed according to the individual patient’s clinical circumstances.
®
®
™
™
®
™
DC Bead and DC BeadM1 are the only drug-eluting beads which have loading with doxorubicin and irinotecan
within their CE-Marked indication statement.
